hey everyone, have a question regarding the throttle position sensor. Mine seems to have shit itself twice in the last month. Im running a aftermarket ecu etc with 12 pound boost, when hitting about 4 and a half rev's the car backfires and backs off, seems to happen more in higher gears then any other gear. kind of like a jerk and black smoke shoots out, not to mention a LOUD backfire. Its certainly not boost cut or any sort of protection as iv had the laptop hooked up with the tuner going through it. The last time we had this problem the TPS was causing the problems with its mixture as the throttle was stuck open (as if the pedal was all the way down), but i cant imagine that another TPS can wreck so easily after only a week or 2. Now are the TPS obsolete or can i still purchase a brand new one? or even use another tps from another car? want to narrow this problem down asap, dont want to add any unnecessary damage to the beast =P
cheers =P
